Stening® High Pressure Stent
With a more robust wall, this model is very resistant to max compression.
When any stent is put under a strength test that compresses it with loads that increase gradually, the stent’s paulatine deformation takes place until it reaches the cession point. Here, the prosthesis suffers a higher deformation, with a notorious reduction of its radial resistance to flattening. This is called the break point, which is about 900 g/cm2 in a classical stent.
In the Stening® High Pressure Stent the tolerance to compression increases surpassing the 2000 g/cm2.
Its wall’s thickness increase is accompanied by an inevitable reduction in the area available for air flow.
- Tracheal neoplasms with a solid extrinsic compression
- A severe tracheal compression that occurs again after the dilatation
- In replacement of a classical stent that collapse by extrinsic compression
